Wow! Gradygal must have decorated my unit as well!
We also have TP dispenser located on the inside of the undersink cabinet door, & 2 Command hooks on the sliding door are where we keep the towels. We have a small, clip-on towel bar that slips over the top of the undersink cabinet door for a hand towel (another in the kitchen @ cutting board door for dish towel). The shower has a suction cup mounted carry-all that has a couple of hooks for wash cloth, loufah (yes, I said loufah!) awa holding our shampoo/conditioner/body wash.
In the kitchen sink, we changed out the sprayer for a filtered water tap - filter mounted under the sink - directly across from coffee pot storage.
Replaced the plastic drawer rollers (3 of 4 were cracked already) under the bed (I don't think you have that in the newer model!) w/metal slide mounts. DW found some neat, coated wire rack type shelving units of all different sizes for all the cabinets incl ouuside storage.
